It is just bins.

And a year and a half of normal ongoing N4 process tweaks likely increasing yield over time, so they now have capacity to do a high volume part like this.

One half of the puzzle seems solved, now I wonder if the rumored 2X3D or X3D2 epeen halo will come to pass.
 
It's possible it's a new stepping that let them tighten it a bit, not on the process side but on the design side.

Could also be just binning. We won't know until someone gets one and reads the stepping out of it.

I strongly doubt this. What are you basing this on?

I was basing it on my hunch is that the clock speed deficit between 9700x and 9800x3d was not based on CCD binning but on something else, related to V-Cache.

MLID says that there is a new Zen 5 stepping, which would confirm what was only a hunch on my end. But their analysis seems to have missed missing the main point of no clock speed deficit due to V-Cache.

 
Hey. I didn't say it was better. I said if you tune it to within an inch of it's life, and failing y-cruncher, and give it all of the watts, you can eek out a few wins on games with a working set that fits in the 2-3 MB range and pull reasonably close in several others.

So whats the point. It's means nothing.

How is the multicore score for 9850x3d lower than most of the 9800x3d submissions?

Something wrong / unoptimized with the setup if a 9850X3D loses to a 9800X3D

Looking at this from a purely overclocking / hwbot lens:

9850X3D is a superbinned 9800X3D, how much better the silicon quality on the CCD is, depend on what sample you are comparing it against.
The very best 9800X3D can probably match it / get close, but there are very few of this caliber out there in the wild.
Average sample vs average sample i would say + ~200-300mhz clockspeed once overclocked
(difference is larger when running stock 5.2ghz vs 5.6ghz like reviewers do)

So the 9850X3D is just a way to get very strong silicon, without binning hundreds of 9800X3D's
IO-die quality (IMC/FCLK) is still all random, so no guarantee there.

If your average user already own a 9800X3D it makes very little sense to buy a 9850X3D
These new cpus are for overclockers or ppl that are building new systems.

When it comes out, most of the reviews will be running stock clock speeds but we will get apples to apples memory clock speed comparison (rather than memory running at 4800, that the GB run showed).

I am curious if (or by how much) the ST results change when running at least normal (DDR5-6000) rather than suboptimal settings. MT results should change more but I am more curious about ST.
